Abstract:

The purpose of this experimental feature was to test the effectiveness of an insulated conventional embankment with reduced Air Convection Embankment (ACE) shoulder top-widths with varying top widths over a section of the Dalton Highway being realigned at MP 219 over thaw-unstable ice-rich permafrost in the foundation soils. This experimental feature consists of twelve test sections with varying shoulder widths, heights, and ACE classes. Amongst these test sections, shoulder widths range between 3 feet and 8.5 feet, shoulder heights range between 5.5 feet and 27.5 feet, and ACE class sizes consist of 3 inch to 5 inch (Class I) and 5 inch to 8 inch (Class II) installed in 2017 and 2018. The locations were monitored for 3 years and data probes collected were analyzed. The results of this study suggest thermal performance of an ACE shoulder embankment is largely a function of embankment height, followed by, in order of decreasing influence, ACE class size and shoulder width.
